Abstract: An acquisition method for data in a wireless body area network and a central device, the acquisition method includes: a central device acquiring topology structure information of a network formed by node devices, and according to the topology structure information of the network determining time slot information about a super-frame; after time slot information is published, acquiring service data packets of an Exclusive Access Phase EAP, a Random Access Phase called RAP and a managed access MAP1 phase in sequence; acquiring packet loss information in the MAP1 phase, and allocating time slots of a managed access MAP2 phase according to the packet loss information; and after the allocated time slots are published, acquiring service data packets in the MAP2 phase according to the allocated time slots. The technical solution can realize the reliable transmission of data in a wireless body area network and reduce the power consumption and time delay.
